Identifying a New Gauge Structure of Dark Matter at the LHC

From power spectrum analyses of the cosmic microwave
background observation, we know that particles in the
Standard Model (SM) contribute about 16% out of the
total matter density of our Universe. To explain the un
known 84%, non-baryonic dark matter was introduced.
With extensive searches for dark matter in various
experiments, it would be interesting to determine the
structure of the gauge group in the dark sector and its
phenomenological effects on observations. This raises
another important question: how does dark matter gains
its mass? As we know that particles in the SM get mass
from interaction with the Higgs particle, it is natural
to consider a new gauge structure in the dark sector in
terms of dark matter mass. In this article, we cover dis
tinct features, depending on dark gauge structures, of
the dark matter signature at the Large Hadron Collider
(LHC).1
